She has gone very quiet on Facebook since her interview, and is complaining to Scottish newspapers that the interview didn't go the way she thought it would and Piers was too aggressive.
I cannot believe from her Facebook ramblings she has not been sectioned or put in prison alone! Forget about the Martha stuff, this isn't the first time she has done this, she has form for stalking over the past couple of decades.
Is Gadd culpable? Yes to some degree, is this woman mentally unwell? Without a shadow of a doubt. She needs some serious inpatient time.
